Chemical Structure
Description
CATO supplies 1-(2-Chlorophenyl)-2,3-butadien-1-one (CAS 196952-95-1), a certified reference material (molecular formula C10H7ClO, MW 178.61 g/mol) for analytical method development and quality control.
1-(2-Chlorophenyl)-2,3-butadien-1-one (C10H7ClO) contains a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 1-(2-Chlorophenyl)-2,3-butadien-1-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
